APPARATUS FOR SINKING AND REMOVING PILES.

SPECIFICATION forming part of Letters Patent No. 227,484, dated May 11,1880.

' Application filed January 6, 1880.

To all whom it may concern:

Be it known that l, HENRY OASE, of Brooklyn, in the county of Kings andState of New York, have invented a new and Improved Apparatus forSinking and Removing Piles and Submarine Obstructions, of which thefollowing is a specification.

Figure'l represents a reduced vertical side elevation of the apparatusin position for sinkinga pile. Fig.2 is a front elevation, enlarged, ofthe apparatus as used in Fig. l. Fig. 3 represents a plan of the sameapparatus in position for sinking a pile. Fig. 4 represents a verticalelevation of a single tube. Fig. 5 is a reduced representation, showingthe method of sinking a submarine bowlder by means oi the single tube.Fig. 6 is a vertical elevation of a wooden pile provided with shoes andsurrounded with tubes, whereby the method of sinking the pile may beapplied. Fig. 7 is a transverse section on line z z, Fig. 6.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a novel and simple apparatusfor sinking piles for submarine foundations and for removing sunkenpiles and other submarine obstructions.

This invention consists of devices composed of one or more tubes withsuitable couplings, by means of which forced or induced currents ofwater may be made to create auxiliary currents to act directly upon thesubmarine bottom beneath and about piles or other, objects, whereby thesand, mud, gravel, &c., are washed away, so that the pile or obstructionmay be sunk, or so that it may be more readily raised, because of theremoval from about it of the adhering mud, sand, gravel, 85o.

In the drawings, A represents the river or harbor bed; B, the water, andO a pier, on which is a steam-pump, D, connected by a pipe, a, to thepile-sinking apparatus E, that is set about the pile F. Saidpile-sinking apparatus E consists, in this instance, of three parallelupright tubes, b b, that extend the entire length of the pile F, and areconnected at their tops and bottoms by suitable tubular couplings c c,as shown, said couplings serving to hold the tubes b b in position aboutthe pile F, and at the same time to determine an equal tlow ot' waterthrough each of the said tubes b b.

A fourth tube and couplings may be connected with those herein shown inFigs. l, 2, and 3, so that the pile F shall be inclosed on all sides bythem; but the number herein shown is more convenient for their readydisengagement from about the pile, to which they are held by a yar'n orrope, d, in the manner shown in Fig. 3.

The pile F, being set vertically, as shown in Fig. l, with the tubes bI) secured about it, is held in that position by the encirclinghalfgromniet j', strung with balls to prevent friction, and on i he headof the said pile F is placed a weight, (shown in dotted lines at g, Fig.1,) whereby the said pile is forced downward as the soil is removed frombeneath its lower end, and the soil is removed from below the said pile,as shown in Fig. 1, by the disturbing and washing action of currents ofwater, that are forced downward through the tubes b b by a force-pump,as indicated in Fig. l, and by the auxiliary or co-operative currentsthat are thereby induced in the water about the said pile, or by thecurrents that are induced upward in the said tubes by the operation of asuction-pump applied to the said tubes b b. When the pile is sunk to itsrequired depth the ropes or yarns d are removed and the whole sinkingapparatus E is drawn up for further use, and the lsoil quickly settlesabout the foot of the pile and holds it in place.

In Fig. 5, 7L h represent pipes grouped about a pile whose downwardprogress is arrested by a bowlder, t', and in this Fig. 5 is alsoindicated the method employed oi removing this bowlder obstruction.Herein is shown, on a reduced scale,'the single tube G, (enlarged inFig. 4,) through which a current ot' water, S, is iiowing underpressure, and, in combination with the created co-operative currents, iswashving the-soil from beneath the said bowlder i,

so that said bowlder may sink or fall still lower and out of the way ofthe piles h h.

In Figs. 6 and 7 are shown a wooden pile, M, provided with shoes N,nia-de of strips of wood m, fastened in contact with each othery acrossthe faces of the pile. The reservoir O, set on top of this pile M, isprovided with a movable screw-cover, a, and a connecting-pipe, 0, sothat with the cover secured in place this apparatus may be used for theapplication of IOO water under pressure from a force-pump, or for theupward induction of currents of water through the tubes P by means oi.'a suctionpump, p, or, with the cover removed, it may be used for theapplication of water without pressure. From this reservoir O the tubes Pextend downward on either side of the said pile M, as shown, to itspoint, or thereabout, and by means of currents of water induced in thesetubes P by pressure or otherwise, and by means of the auxiliary currentsinduced by them in the surrounding water, the soil may be removed frombeneath and about the foot of the pile M, so that the said pile willreadily sink to position, and when the pile is in position the reservoirO and attached tubes P are removed, as are the reservoir and tubes fromthe hollow pile K, when that is, by like means, sunk to position.

In removing sunken piles, the single tube G maybe used in the samemanner in which it is shown in use in Fig. 5, whereby, by means of acurrent of water forced or induced through the said tube and creating(3o-operating currents,

the soil may be removed from about the foot of the sunken pile, so thatthe said pile may readily be drawn up; or groups of tubes H or P,respectively, with their attached reservoirs, may be used for creatingand applying the watercurrents for the removal of the soil from aboutthe piles.

Having thus described my invention, I cla-im as new and desire to secureby Letters Patent- As a means of sinking or removing piles by the use ofwater, the pile sinking and removing apparatus E, consisting of theparallel tubes b b and couplings c c, substantially as herein shown anddescribed.

HENRY OASE.
